On the Solar Component in the Observed Global Temperature Anomalies

TL;DR

This study analyzes how solar activity, indicated by sunspot numbers, significantly influences global temperature anomalies and may determine future temperature trend changes.

Contribution

It demonstrates the significant impact of solar activity on global temperature anomalies using updated data and highlights its potential role in future temperature trend shifts.

Findings

Solar component significantly affects temperature anomalies

Solar activity influences the stationary behavior of anomalies

Future temperature trends depend on solar activity behavior

Abstract

In this paper, starting from the updated time series of global temperature anomalies, Ta, we show how the solar component affects the observed behavior using, as an indicator of solar activity, the Solar Sunspot Number SSN. The results that are found clearly show that the solar component has an important role and affects significantly the current observed stationary behavior of global temperature anomalies. The solar activity behavior and its future role will therefore be decisive in determining whether or not the restart of the increase of temperature anomalies observed since 1975 will occur.
